Do you prefer to use stablecoins that conceal your transaction details from the public blockchain?
Fairblock has officially launched its CUSD stablecoin on the Arbitrum network. This privacy-oriented asset is built upon PYUSDx and enables users to hide transaction amounts and account balances.
Why it matters
The project aims to protect sensitive financial operations such as payroll, treasury management, and over-the-counter settlements. By shielding payment details, Fairblock seeks to provide enterprise-grade confidentiality for on-chain accounting.
CUSD utilizes PYUSDx as its core underlying architecture to facilitate private transfers. While public transfers are supported, the stablecoin architecture enables the obfuscation of payment amounts and balances.
The players
Fairblock
A developer of privacy-focused financial infrastructure and decentralized ledger protocols.
Arbitrum
An Ethereum Layer 2 scaling network designed to improve transaction speed and reduce costs for decentralized applications.
PayPal
A global payments platform and financial services provider that issues the PYUSD stablecoin.
MoonPay
A financial technology company providing infrastructure for fiat-to-crypto payments.
The details
The CUSD stablecoin operates on the Arbitrum network, a Layer 2 scaling solution that sits atop Ethereum to increase transaction throughput. By leveraging PYUSDx, a derivative of PayPal’s stablecoin technology, the system applies cryptographic privacy features to ensure that sensitive financial details remain hidden from public view during transactions. This allows users to conduct payroll and treasury management activities while maintaining the privacy typically found in traditional banking systems.

The Tech Race
This project builds directly upon the foundational infrastructure of PYUSD to capture the enterprise demand for private on-chain settlement. It represents a shift from general-purpose retail stablecoins toward specialized, confidential financial tooling.
Businesses involved in treasury management and payroll will be the primary early users for these privacy-enhanced transfer features. Interested parties should watch for upcoming technical disclosures regarding the planned economic incentives for early adopters.
The takeaway
Fairblock is targeting a major enterprise pain point by bringing private settlement to the Arbitrum ecosystem. Readers should monitor upcoming documentation for specifics on how the incentive program will function for new users.
